This is a set of volumes 1-11 of "Healthy, Cultural, Minimum Standard of Living." I bought these but haven't had a chance to read them, so I'm putting them up for sale. I opened the books to check their condition, but I haven't opened the pages, so they should be in good condition. Please refrain from purchasing if you are overly concerned about the fact that they have been opened. By Haruko Kashiwagi
